That's about it. I don't know where you heard that liveaquaria LR was not good. That's simply false. They are not as cheap as some places but they do have hight quality LR.
Fill the tank about half full and add water, the heater and power head. When you get to your temp, add salt mix to get it to 1.025. Put the base rock down, add the sand, add the LR (if you can see) and add mixed sw to complete filling the tank.
